Kyoya Ida is a hard-nosed detective from the Shinjuku Police precinct. He is known in the force as an unreasonable type who would use lethal force to solve cases, making him unpopular with the enlisted and high-ranking officers in the National Police Agency.

Despite this fact, there are some in the force that admire Ida for his bravery and cleverness in using lethal force to solve criminal cases whenever legal means are met in a dead end.

There is a big differnence in the quality of the several cases. Some are ingenious others quite unrealistic and even dumb. Half of them have a great storyline and interesting characters but the rest is only so-so, especially when Jiraishin is in foreign countries the quality drops drastically. But, the protagonist is very interesting, cold and untouchable, in the whole manga you can't figure out his feelings and thoughts. After a while this is a litte bit tiring because you don't learn anything about Jiraishin or his motives, the whole series he remains a mystery. What I really like is that there are many film noir elements in this manga and they are used quite well for the atmosphere.

Besides me finding Ida to be quite attractive because of his villain looks, I honestly liked how he came to solve each problem in a different way. There was never a repeat as to how he deals with an issue. It was probably because all the problems he got into are not similar in any particular way. It went from a twin sister committing suicide to refugees on a snowy island to dealing with an ex-military convict. Basically, in Ida's world, everything isn't always about bunnies and sunshine. This is the dark reality.

One of the best manga I've ever read!!! Tsutomu-sensei really knows how to dig into the darkest places of human mind. The plot is painfully beautiful, thouhg most of the stories have a tragic end. The "blanc et noir" artstyle rocks; it goes well with the main theme of the manga. Iida Kyoya and Eriko Aizawa are among my favorite manga characters! Especially Iida - his idiosyncrasy makes me shiver with excitement!!!

the main character is the major draw of this series IMO. He is cool in any interpretation, being calm and collected at whatever that happen. he is 'cold' but he is not freezing - you can see some of his humanities leaked out here and there when he deals with the people in his his own way. when i first read this manga i can't get past the first chapter because i felt he is too cold, but with experience i come to appreciate characters that do not fling out their emotions unnecessarily. aside from mc, other characters are also easily likable, and you came to be quite attached to some of them. however, DO NOT expect just because they are important or they have been hanging around for several volumes they are safe - the only safe person in this manga is the protagonist.

i do like the cases here since they are mostly different from other detective manga i had read. however, i do think most of them are unrealistic, and some even get into the world of psycho mumbo jumbo that i do not think should exist in sombre piece like this manga. and frankly, ida is quite a god mod character since i just don't think a person can take on an entire mafia/gangster/triad/ yakuza by themselves, but he can do it with nary a sweat. so i feel most of these cases is not realistic and just 'awesome' and 'cool' so don't expect too much from them.

the art is pleasing. i really like Ida's character design, his 'cool' expressions and his swanky outfit is great to look at. overall art match with the atmosphere and the story. i like that though there is copious amount of blood there is not much gore, it keep the focus of the story on the characters and the case.

this is really a great manga, but one need some experience with the manga world so one can become jaded and bored with normal protagonist to appreciate someone such as Ida.

Characters that appear cold or indifferent are fine with me generally because I know that though they may not show it they do have emotions. However, I found myself searching and searching for a hint of compassion in the protagonist. All I needed was a hint to let me know he was human deep, deep, deep down. And because I didn't find one, I'm not sure that there's anything more to him than that coldness. As far as I'm concerned, he can pragmatically kill as many people as he needs to, so long as I have that reassurance. Since I don't, there's nothing to engage me with his character.

It is addictive, entertaining, thoughtful and pretty clever manga. Characters and situations are so realistic you can see it all play in your head like a film. Protagonist is pretty interesting fellow, always surprises with his actions. A must read, I can guarantee there is not a single boring page from start to end. Only sad thing with it is that its short (at least for me) .

This is one of the most addictive stories i have had the pleasure of reading. The story is amazing, the art is great, the characters, esepically Iida are awesome. This is why this particular mangaka is one of my personal favourites.

But it was missing something which disappointed me, and thats Iida's past, what caused him to be so cold, and what caused him to do the things he does, which had me asking these questions right down to the end. There is a sequel so i hope the author cover his bases with it, but excellent amanga overall.

I like this manga. I liked that the main lead stayed indifferent throughout the whole manga. He didn't have a sudden revolution and change into an idealisitc, empathatic protagonist, he stayed as he was. I liked how the female lead stayed understated; she acted like a mature woman and there was no drama between her and the male lead, so the focus was kept on the cases. One of the problems, for me, though, was that the cases didn't seem quite finished when they were finished. It could just have been the author leaving it open-ended, but there was always an uncomfortable jerk in the story when I realised after a few pages into a new chapter that it was a new case. Most of the cases, if not all, focused on strange, out-of-the-ordinary murderers. Although this is needed to keep the series interesting, it wouldn't have done any harm if a few of the first cases had been a bog-standard murderer with nothing special.There are few mangas about detectives, and even fewer which are more mature, than, say, QED and CMB (which in themselves aren't about a detective at all). It doesn't deal with the supernatural, it is, quite plain and simply, a manga about a detective.

damn this manga deserves the perfect score. The cases solved in this detective manga are very unique and will leave you speechless until the very last page. It's dark and full of suspense catch the killer save the victim thing. The main protagonist is damn cold and will not hesitate to kill. Probably the best detective manga out there. btw thanks to Hawks by bringing this manga out there
